Phytochemical Screening and Green Synthesis of Silver Nanoparticles Using extracts of Thunbergia coccinea Wall

World plant biodiversity is the largest source of herbal medicines which are being used since the ancient ages in traditional health care system. Phytoconstituents are the natural bioactive compounds found in plants. The present study was carried out to screen phytochemicals like carbohydrates, tannins, steroids, saponins, alkaloids and flavonoids in the leaf and floral extract of Thunbergia coccinea wall. Phytochemical screening of extracts was carried out according to the standard method. The ethanolic extract of both parts of the plant were qualitatively screened for phytochemicals by using standard procedures which revealed the presence of various important bioactive chemical entities.
